This, I believe, was commit 345bd7ebbb38f0e1d5acf33ab3f680111cfa7871 where
LEN_TRIM was introduced to interface mapping on 2016-12-09 for pr44265.
Removing the chunk concerned does not fix the problem.
I have stared at this for ages. For reasons that I cannot see, the use
associated version of 'c' is being used, so the interface mapping has failed.
I will come back to this.
Paul
